Title: David M. Stubbs: Innovator in Optical Phased Array Technology
Introduction
David M. Stubbs is a notable inventor based in Mountain View, California. He has made significant contributions to the field of optical technology, particularly in the development of advanced optical phased array systems. With a total of 2 patents, his work has implications for various applications in the aerospace sector.
Latest Patents
One of Stubbs' latest patents is titled "Automatic compensation of optical path for gimbaled phased array." This invention discloses an optical phased array system that employs three methods of phased array retargeting: optical retargeting, element slew, and rigid body array slew. These methods work in a hierarchical manner to minimize retargeting disturbances and enhance system performance by shortening retargeting timelines. The optical train configuration described in this patent provides approximately 97% of the optical path length compensation required for a slew of ±20 degrees from the array normal. This innovation significantly reduces the amplitude required of the piston control mirror, ensuring that an equal optical path length is maintained from the object to the sensor.
Another notable patent by Stubbs is for a "Modulated optical energy source." This invention is capable of operating in the far infrared spectrum and allows for on-off energy modulation without interrupting the radiation source's operating temperature characteristics. The design includes provisions for radiant energy dissipation as part of the modulation process, achieving uniform output beam dispersion over a specified area.
